I changed this to print MAC address by default. Currently, enetc driver is not supporting
NOTICE type log and the next supported log level is INFO and we are using INFO type log
only while setting the random MAC addresses.
If INFO type log is not ok to print this information, please suggest me. Should I add NOTICE
Type log? Or just add a printf to display the MAC address.
